Old site, and it isn't like a flash programmer
it's just the burning the roms to eproms and solder those on an existing cartridge.
kinda like, how to make Neo-Geo AES games to MVS
1. Not everybody can solder
2. Not everybody has a eprom burner
3. you need to fuck up other snes carts
4. if you do fuck up the soldering, you lost a real game cart
5. not everybody has all the labels lying around
6. Doesn't work with all games (you can't take an snes and replace the chips (DSP1, DSP2, SUPERFX, etc...)
1. It's a nice way to get game carts you can't find cheap (however i've neer seen expensive snes games anyway)
2. you can burn hacked roms (trained, translated, etc...) to eprom and play
3. Superflash doesn't play all games iether
Etc...
well i'll prefer a flashkit _________________ He, who controls the spice, Controls the UNIVERSE

Dunno about that, I've seen Willem Eprom programmers for under $100 on Ebay. |

Just go to willem.org. They've got their newest kit for 78Euros...
http://www.willem.org/epromshop.html
or build the programmer yourself...
http://www.mikeg2.freeserve.co.uk/eprom/eprom.html
You see, it's not thaaaaat expansive after all. I prefer using my SuperFlash if I test some hacked roms or some betas (cause the EEPROMs are quite expensive...). If I want a translated game or a very good finished hack on a real cart, I prefer doing it the Snesdev's way^^ |

I was motivated by that very site to build a few carts. I made two Starfox2 carts for example, which are not playable on my flash cart. |

If you're interested in building a couple more of those carts using the Dragon Quest 5 & 6 translated patch, drop me a PM so we can discuss the price. |

SNES ROMs do not follow the standard (JEDEC) pinout. You must make adapter boards to read them with a programmer... Personally, I think that's a waste of time since there are better ways to dump SNES carts. |

1) Remove the SMC header (first 512 bytes)
2) Program it to a EPROM
3) Modify cartridge PCB to use EPROM (compare pinouts and cut changed tracks, and wire new tracks) |

You only remove the first 512 bytes if it's a header! Make sure the game is 131072*n bytes large and not interleaved. (you should just convert it to binary using ucon64)
The ROM image size needs to be 2^n to fit into a EPROM. If the game is 10M, you must separate it into 8M + 2M, or 12M = 8M + 4M or 20M = 16M + 4M, 24M = 16M + 8M etc.
If your game has SRAM, you will also need to add a SRAM circuit which depends on the game you were going to build...
If you build a LoROM PCB, you cannot change it to HiROM later... The same goes for the opposite. |
